Ok, I have my business idea and have come up with the perfect name. The only trouble is that whilst no one else is using it for a business within my sector, one of the large cosmetic giants has the trademark for that name which doesn't run out until 2027. It is the name of one of their products that is now discontinued so perhaps unlikely to be used by them again but who knows?
Would I be totally mad to use it? My business is related to dermatology and the products are skincare products but I don't think anyone would get confused between the two.
Where do I stand legally? Or should I just pick another name altogether?
